My baby is 3 and a half months old and as of recently, whenever I put him down to sleep, instead of a startle, his legs just bend up towards his stomach🙁 over and over and over. He bends them in, and then puts them back down slowly and not even a second later they go right back up. I have no idea what’s up with that. The only way he slept last night, was with some of my blanket which is thicker and slightly heavier on his legs and my hand over his legs too. And even with that I would feel them try to go up but once they met with the weight of my hand they’d stop. What is that and how can I help to get it to stop??? It wakes him up after a while!🤕
